The vehicle's battery will quickly run out if the transceiver transmits while the vehicle's engine OFF. AVOID placing the transceiver in excessively dusty environments. AVOID placing the transceiver against walls. This will obstruct heat dissipation. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they damage the transceiver surfaces. BE CAREFUL!The transceiver will become hot when operating continuously for long periods. · Be sure to bend the flat cable in the correct direction, before turning over (inverting) the transceiver. 5 CONNECTION AND MAINTENANCE 2 D Mounting the transceiver The universal mounting bracket supplied with your transceiver allows overhead mounting. · Mount the transceiver securely with the 4 supplied screws to a thick surface which can support more than 1. 5 kg. Flat washer Spring washer When using self-tapping screws 6 2 CONNECTION AND MAINTENANCE I Optional UT-109/UT-110 installation Install the optional UT-109 and UT-110 as shown below: q Turn power OFF, then disconnect the DC power cable. t Install the scrambler unit. r Cut the print pattern on the PCB at the TX mic circuit (A) and RX AF circuit (B) as shown below. Front panel y Replace the bottom cover and screws, then the DC power cable. B NOTE: Be sure to re-solder the disconnected points at left, otherwise no TX modulation or AF output is available when you remove the scrambler units. 7 CONNECTION AND MAINTENANCE 2 I Optional OPC-617 installation Install the OPC-617 as shown below. I Antenna A key element in the performance of any communication system is an antenna. Ask your dealer about antennas and the best places to mount them. I Fuse replacement Two fuses are installed in the supplied DC power cable. If a fuse blows or the transceiver stops functioning, track down the source of the problem if possible, and replace the damaged fuse with a new rated one. Fuse rating : 15 A (IC-275H/F620), 20 A (IC-F621) OPTIONAL CABLE PIN ASSIGNMENT trewq q LCD backlit cont. GND I Cleaning If the transceiver becomes dusty or dirty, wipe it clean with a dry, soft cloth. AVOID the use of solvents such as benzene or alcohol, as they may damage transceiver surfaces. oiuy 8 2 CONNECTION AND MAINTENANCE I Options SP-22 EXTERNAL SPEAKER Compact and easy-to-install. Monitor switch is equipped. OPC-617 ACC CABLE Allows you to connect to an external terminal.
